Resum:

The analysis of the interconnection status-quo between content providers and Internet Service Providers (ISPs) is essential to understand the evolution of the Internet ecosystem. In the last years we have witnessed a spectacular increase of Internet traffic, especially multimedia content, which has driven both content providers and operators to rethink their interconnection models. This thesis performs an extensive traffic analysis from two perspectives to understand the rationale behind the Internet players. First, we analyse the traffic from the perspective of the evolution of the Internet protocols. Analyzing the protocols we pretend to observe whether the traffic pattern has changed while new applications have emerged and the demand have exploded. Second, we collect a dataset of Internet traces to evaluate the connectivity between access ISPs and the most popular content providers. Analyzing the Internet traces we want to identify the correlations in the interconnection models that different Internet players use.
